目前許多移動播放裝置(例如:無線喇叭、無線螢幕、手機、平板電腦、無線耳機等等)均具有中央處理器與連網能力,這些裝置只要能取得播放內容的網址(Uniform Resource Locator,URL),它們本身就足以當作獨立的播放系統。然而,當這些裝置脫離原本的網路範圍後,先前技術無法令它們繼續播放;另外,當這些裝置的位置改變後,先前技術也無法依它們當前的位置來調整它們的播放角色。鑑於上述,本揭露提出一種網路資料播放系統與方法,能夠讓一播放裝置在脫離原本的網路範圍後繼續播放原網址的內容;另外,本揭露也提出一種播放系統與方法,能夠在一或多個播放裝置的位置改變後,調整它的/它們的播放角色(例如:在一對藍牙耳機的左聲道裝置與右聲道裝置在交換位置後,交換它們的播放角色)。依定位精確性的需求與應用情境,一已知或自行開發的室內或室外定位技術可被本揭露之實施例直接地或間接地用來偵測播放裝置的位置;舉例來說,該定位技術是已知或自行開發的 Wi-Fi定位技術,其最大定位誤差可達2米以內;或是已知或自行開發的藍牙定位技術,其最大定位誤差可達1米以內;或是已知或自行開發的超寬頻(Ultra-wideband,UWB)定位技術,其最大定位誤差可達1~2公分以內。更多定位技術的介紹可見於下列網址:(1)https://kknews.cc/zh-tw/tech/2bznyr.html;(2)https://arxiv.org/pdf/1709.01015.pdf;(3)https://en.wikipedia.org/wiki/Wi-Fi_positioning_system;(4)https://www.leverege.com/blogpost/wifi-indoor-positioning;(5)https://pdfs.semanticscholar.org/8e72/61a54be0cdc66b15b111046057859b9c88eb.pdf;以及(6)https://benevo.pixnet.net/blog/post/66881109-。 At present, many mobile playback devices (such as wireless speakers, wireless screens, mobile phones, tablets, wireless headsets, etc.) have a central processing unit and networking capabilities. These devices only need to obtain the URL of the content to be played (Uniform Resource Locator, URL) , They are sufficient as independent playback systems by themselves. However, when these devices are out of the original network range, the prior art cannot make them continue to play; in addition, when the location of these devices is changed, the prior art cannot adjust their playing roles according to their current location. In view of the above, this disclosure proposes a network data playback system and method, which can allow a playback device to continue to play the content of the original URL after leaving the original network range; in addition, this disclosure also proposes a playback system and method that can Or after the positions of multiple playback devices are changed, adjust its/their playing roles (for example: after the left channel device and the right channel device of a pair of Bluetooth headsets have exchanged positions, their playing roles are exchanged). According to the requirements of positioning accuracy and the application context, a known or self-developed indoor or outdoor positioning technology can be directly or indirectly used by the embodiments of the disclosure to detect the position of the playback device; for example, the positioning technology Is known or self-developed Wi-Fi positioning technology, the maximum positioning error can reach within 2 meters; or the known or self-developed Bluetooth positioning technology, the maximum positioning error can reach within 1 meter; or the known or self-developed ultra-wideband (Ultra -wideband, UWB) positioning technology, its maximum positioning error can reach within 1~2 cm. More information on positioning technology can be found at the following URL: (1) https: //kknews.cc/zh-tw/tech/2bznyr.html; (2) https: //arxiv.org/pdf/1709.01015.pdf; ( 3) https: //en.wikipedia.org/wiki/Wi-Fi_positioning_system; (4) https: //www.leverege.com/blogpost/wifi-indoor-positioning; (5) https: //pdfs.semanticscholar. org/8e72/61a54be0cdc66b15b111046057859b9c88eb.pdf; and (6) https://benevo.pixnet.net/blog/post/66881109-.

步驟S740:比對該分佈樣式與複數個預存模式的樣式的至少一部分,以選擇該些預存模式的其中之一作為一播放模式。 Step S740: Compare the distribution pattern with at least a part of the patterns of the plurality of pre-stored patterns to select one of the pre-stored patterns as a play mode.
上述比對可藉由已知或自行開發的模式識別(pattern recognition)技術來實現;複數個比對結果中誤差最小者或符合一條件(例如:誤差門檻,或使用者設定的條件)者所關聯的預存模式,可作為該播放模式。舉例而言,步驟S710所選擇的資料是音訊資料,該些預存模式包含一基本模式(由前左、前右與中央喇叭構成)、一環繞模式(由前左、前右、中央、
環繞左與環繞右喇叭構成)與一加強環繞模式(由前左、前右、中央、環繞左、環繞右、環繞後左與環繞後右喇叭構成),該些預存模式的樣式的每一種是以相對座標資訊來表示,因此,藉由比對該分佈樣式與該些預存模式的樣式,主控裝置610可判斷出圖6之從屬裝置620的分佈樣式最近似於該基本模式的樣式,從而主控裝置610會選擇該基本模式作為該播放模式。
The above comparison can be achieved by known or self-developed pattern recognition (pattern recognition) technology; a plurality of comparison results have the smallest error or meet a condition (for example: error threshold, or conditions set by the user). The associated pre-stored mode can be used as the play mode. For example, the data selected in step S710 is audio data, and the pre-stored modes include a basic mode (consisting of front left, front right, and center speakers), and a surround mode (consisting of front left, front right, center,
Surround left and surround right speakers) and an enhanced surround mode (composed of front left, front right, center, surround left, surround right, surround back left and surround back right speakers), each of these pre-stored modes is It is expressed by relative coordinate information. Therefore, by comparing the distribution pattern with the patterns of the pre-stored patterns, the
步驟S750:依據該位置資訊與該播放模式決定該些從屬裝置的播放參數,以決定該些從屬裝置播放該資料的效果;或者告知該些從屬裝置依據該播放模式與該位置資訊所決定的角色資訊,以使該些從屬裝置據以決定它們的播放參數。 Step S750: Determine the playback parameters of the slave devices according to the location information and the playback mode to determine the effect of the slave devices to play the data; or inform the slave devices of the roles determined based on the playback mode and the location information Information so that the slave devices can determine their playback parameters.
舉例而言,主控裝置610依據該位置資訊與該基本模式,決定從屬裝置622、624、626分別為前左、中央與前右喇叭,並據以決定前左喇叭的播放參數(例如:100%左聲道)、中央喇叭的播放參數(例如:50%左聲道與50%右聲道)與前右喇叭的播放參數(例如:100%右聲道)。另舉例而言,主控裝置610依據該基本模式與該位置資訊,告知從屬裝置622、624、626它們分別為前左、中央與前右喇叭,並讓從屬裝置622、624、626依據它們的角色,藉由同一/不同演算法來決定它們自己的播放參數。再舉例而言,該些從屬裝置620的至少其中之二的播放參數是不同的。值得注意的是,主控裝置610可選擇性地控制該些從屬裝置620同步地播放該資料。
